Answer #1

Redox reaction mean the reaction in which both oxidation and reduction of atom, compound or molecule takes place

From the following in 4th reaction O2 is oxidized to H2O and H+ and NH4+ is reduced to NO3-

And in 5th option Na atom is oxidized and Cl2 is reduced

So option 4 and 5 is correct
